Application led December 8, 1923. Serial No. 679,383.7:

` y To all 'whomt may concern.

Be it known that I, FREDERICK DIETRICH, a citizen-of the United States, 'residing at Flushing, in the county of Queens and State of New- ."Xork, have .invented a. certain fnew and usefulilmprovement inHeadbands for Telephone `.Head Sets, of whichthe ,following is a specification. Y

' M inyention'relates broadly to telephone headets and more parti'zularly to a constructionfof headband for rtelephone headsets.

readily conform to any shape ofA head'.

vAnotherobject. of my Vinvention iQ to provide' a headband for telephone yheadsets in which the. bands comprise. seamless .fabric *webbingy the webbing being pivotally mounted longitudinally upon its center in such mannerthat-'rdliferent sections thereof may assume-different positions conforming with the crown" flthehead orthe irregular contourered fiythe hair of the wearer whereby the band may snugly and comfortably fit upon theheadj-of the wearer.

A still furtherobjectof vthe invention 'is to provide a seamless fabric webbing headband which will be inexpensive in construction and simple Ain manufacture on a quantity production basis.

My invention ,will be more clearly understoodv by referenceto the `following specification and the accompanying'drawings, in which: Figure 'lisa perspective View of my improved headband for telephone headsets; Fig. 2 is a' plan View of'one section of the headband illustrated in Fig. l; Fig. 3 is a side elevation of the headband member illustrated' in Fig. 2 showing the'seamless fabric webbing partially in cross section; and F igs. views illustrating headband may assume in comfortably seein-ing the telephone'headset on the crown llaterallyl 'flexible' -structions theband has been Aexbeedingly uncomfortable when'the telephone headset is worn for any extended vlperiod of timeand the cost` of manufacture has been `relatively high with many inherent difficulties in production on a.- quantity basis. It has alsobeen proposed .to sew strips of cloth or leather on either side support for head telephones. 'In these constructions it is'diihcult tofsew the-material on either side of the band, and there .is a relatively large spaces left Ifree between the band and the material byreason ofthe fact Ithat it is not possible for a needle carrying the thread to be passed uniformly close to the band-'on either'side thereof. "The sewingr of bands of this typelis notonly expensive but the thread has a 'tendency to rot andbreak at different points during the use of the headband, thereby causing the two parts of the band to rip open with the ultimate destruction of the headband. Perspirationand oil fromthe hair of the weaxcr often cause rotting of the'stitches and de` tively stiff throughout their length and therefore become uncomfortable after a 'few hours use. In irregular shapes of crowns these headbands are practically. tangential at some' points whereas at other points they form no support whatever, and by reason of their inherent stiffness will not comfortably 'conform with the crown andv particularly with irregular shapes often arrangement of the hair. dress-of the user, specially the wave formation in a woxnans alr.

My improvement consists in providingaI seamless fabric webbing for headbands. vwhich webbing is 'substantially fiat in cross section with a longitudinal borerunning along the central axis thereof through which I pass a round wire headband support. The seamless fabric webbing material is pivotally mounted on the longitudinal rod in such manner that it may turn readily to con form to various shapes-which condit-ionsmayrequire. The webbing;- is substantially flexible throughout its length so tlmtdieren! portions of the bund may assume dille-rout positions.'

Referring more particularly lo the lr-:iwingjs. reference clmrarturs 1 uml L' indicabihc central circular supporting;r membels of aband forming a .imposed by they which are looped at adjacent ends and curved to conform washers 3 and 4' and 5-and 6 forming-seats for the opposite ends of` the supporting cores. The washers 3 and 4 and 5 and 6 1 may also -suppgrt-'a suitable chuck 7 `and 8 lwould form substantially `by which `the-telephone headset is supported bythe bands. lThe central core members l and 2 define approximately twoseiiii-circles which if ljoined by a theoretical line between the extremitiespf the members 1 and 2 a lune or spherical wedge shapedftheoretical solid or a ligure boundedby twolarcs of circles.` On the centrail circularmembers 1 and 2 Ir locate the seamlessfabri'cv-webbing material 9 and 10.

AThe .seamless-"fabric webbing comprises a substantially flat solid but flexible' woven body having a longitudinal bore 12 extending along thev central axis thereof. This bore 12 is-ofsuflicient diameter to Venable thev centraLcircular members to be inserted 'therethrough 'insuch manner that the seamless fabric webbing pivots about the central circular member throughout the length thereof. The'woven bod extends on each side of the central circu ar member for a distance substantially greater than the diameter of the central member with the surfaces of the webbing lyin -wholly in parallel planes on opposite si es of the central member. At opposite ends of the seamless fabric webbing material I provide metallic U shaped clampv members 14, 15, 16, and 17 each arcuate in cross section in such manner that each may be clamped over the ends of the fabric insuring a permanently at cross section adjacent each end of the band but freely allowing various changes in the cross section 'of the band and independent -fiexure of the webbing intermediate the ends.

In Figs.' 2- and-3 the seamless fabric webbing has been moved longitudinally along A' the central circular member to more clearly bring in the headband, the webbing may assume the arcuate cross section represented in Fig. 5 with a'radius from below. Some other force in a different 'portion of the headband .might require the seamless fabric webbing to assume the contours illustrated in Fig. 6 or 7. At all times the webbing may rotate bodily about the central circular memto grooves in pairs ofA band intermediate t If by reason of some obstruction ber 1 as'represented in Figs. 8 and 9. vStill -other forces may exist along the length of the headband whiehthe headband would comfortably accommodatie by movinginto an arcuate position illustrated in Fig. 10 with aradius above the central circular member 1.,.The various changes in contour of the"v i e ends thereof have leen represented in the perspective view in It will be observed that my headband is constructed in such manner that' there is no tendency to catch or break the hair at' the same time that it comfortably Asupports the telephone headset.

I claim and desire to secure by Letters Patent of the United States is:

1.-A headband for telephone headsets,

l comprising in combination a pair of central circular core members substantially arcuate in contour and joined at opposite ends, a strip of seamless fabric webbingmaterial having a substantially solid woven body carried by each of said central circular core members, said core members passing longi- "4' tudinally through a bore in said seamle fabric webbing, means at oppositeends of said webbing whereby said webbing is maintained substantially flatat said ends, said webbing being free to revolve about said central circular core throughout its length and arranged to assume various contours by independent fiexure of -the webbing intermediate the ends thereof.

2. A. headband for telephonel headsets, I

comprising in combination a pairof central circular core members arranged in arcuate formation and joined at opposite ends thereof, seamless fabric webbing material having a substantially solid woven body pi-votally mounted on each of said central circular core members for lateral movement thereon. a U` shaped member on opposite ends of s aidseamless fabric webbing material, said members being arcuate in cross section and Vadapted to be secured rigidly upon the ends of said fabric' whereby the fabric adjacent said members is maintained substantially flat in cross section while the fabric intermediate the endsof the band may assume various contours by independent flexure of the webbing.

3. A head band for telephone headsets comprising in combination a pair of arcuate wire members substantiallyficircular -in cross section, a woven body of seamless fabric webbing arranged to enclose said wire members, said webbing extending laterally on either side of said wire members for distances substantially greater than the diameter `,of said wire members and having its surfaces lying iii substantially parallel planeson opposite sides of said wire mem- 8 0 Having thus described my invention, what bers 'and arranged for independent ilexure of the webbing throughout its length, whereby said headband 'conforms to the crown of the wearer. v v

4. A head band for telephone headsets Y comprising in combination a pair of arcuate wire members substantial] circular in cross section, a substantiall so id woven body vof seamless fabric web in enveloping said wire members, said we hing having substantially flat parallel surfaces extending on opposite sides of said wire I nexbei's fol` disyizances substantially greater than the diam- .of the webbing throughout the length of the band whereby the webbing snugly conforms to the crown of the wearer.
